What are the blue stars? Why do they change?

The blue stars represent your progress through the levels. You earn stars by buying items in the Island Shop. Every item and its upgrade is worth 1 star. For example, a ship upgraded twice is worth 2 stars total.

If an item is destroyed by being attacked twice, you lose the total star value and have to rebuild it from the beginning.
